摘要: Particle number and mass concentrations were measured in Beijing during the winter summer periods 2003, together with some other parameters including black carbon (BC) meteorological conditions. exhibited low seasonality, ratio of PM2.5/PM10 was higher than that summer. size distribution (PSD) characterized by four modes seasonality. BC well correlated accumulation coarse particles, indicating these particles are related to anthropogenic activities. (except ultra-fine nucleation particles) followed trends concentration for majority day, most associated primary emissions. The diurnal distributions mode two peaks.
